How to find Union of Two Sets in Swift ?

Answer

To find the union of two sets in Swift, you can use the union method provided by the Set structure.

✐ Examples

1 Find Union of Two Sets

In this example,

We create two Set objects, set1 and set2, containing some elements.
We use the union method of set1 to perform the union operation with set2.
After the union operation, set1 contains all the unique elements from both set1 and set2.

Swift Program

var set1: Set<Int> = [1, 2, 3]
var set2: Set<Int> = [3, 4, 5]

let unionSet = set1.union(set2)

print("Union of set1 and set2:")
for item in unionSet {
    print(item)
}

Output

Union of set1 and set2:
5
2
3
1
4

2 Find Union of Two Sets (String Sets)

In this example,

We create two Set objects, set1 and set2, containing some string elements.
We use the union method of set1 to perform the union operation with set2.
After the union operation, set1 contains all the unique elements from both set1 and set2.

Swift Program

var set1: Set<String> = ["apple", "banana", "orange"]
var set2: Set<String> = ["orange", "pear", "grape"]

let unionSet = set1.union(set2)

print("Union of set1 and set2:")
for item in unionSet {
    print(item)
}

Output

Union of set1 and set2:
orange
banana
apple
grape
pear
